"That's a bunch of needlessly cynical and completely ignorant bullshit. We don't use the army to convince people to use dollars. That's quackery. People use dollars because the value is relatively stable, most goods for sale in the U.S. and exported from the U.S. are priced in dollars, people in the U.S. pay their taxes in dollars, oil tends to be priced in dollars internationally, foreign countries hold lots of dollars as reserves, in the U.S. you can have a bank account denominated in dollars that will retain it's value up to $250,000 even if the bank blows up(!), and so on. All of these are reasons people use dollars. It isn't something that's done at the point of a gun."
a) The value isn't stable. Dollars have lost ~90+% of its value since the fed was created.
b) You pay taxes in dollars, because otherwise you'd be thrown in jail by force.
c) Oil doesn't "tend to be valued in dollars". It's an agreement between the us and the saudis, to only sell oil in dollars, in exchange for protection. Leaders of other countries trying to change that, were suddenly found to be dictators, deposed and killed.
d) Foreign countries hold dollars because otherwise they can't buy oil.
e) The bank account doesn't hold it's "value" of 250k. It holds its nominal price.
Finally, because of the oil thing, the us has been happily printing dollars, and exporting its inflation to the whole world, stealing everybody.
Sorry, but you are the ignorant.
